AMD Developer - AMD CodeAnalyst

CodeAnalyst, on Fedora16, AMD FX-8150

diegor1982 — 2012-01-11T13:54:09 -05.00

Hi everyone,

We've got an FX-8150 at the lab, running on Fedora 16.
I got stuck in installing the latest CodeAnalyst CodeAnalyst-3_1_4_0230-Public.tar.gz
by calling ./CAInstaller.sh (see below my settings).
Apparently, ./configure (called inside ./CAInstaller) does not complain about anything but it does not generate a Makefile (see below my output).

Funny enough, the compilation of Oprofile 0.9.7 was super smooth (configured with --with-kernel-support ./ophelp was giving me all the hw perfctr, IBS's included).

Does someone have an idea about how to fix this?

Thank you in advance!

Diego

System graph and System tasks tabs missing

milos — 2012-01-01T17:56:12 -05.00

I installed CodeAnalyst 3.1.4 (newest version) today, using the RHEL5U6 RPMs, as well as the Kernel Modules. I used command rpm -iv rpmname, and set up the permissions, paths, etc.

It seems to work fine, but while the manual:

http://developer.amd.com/tools/CodeAnalyst/codeanalystlinux/assets/CodeAnalyst_linux_users_guide-1.0.pdf

suggests that there should be three tabs ("System data","System graph", and "System tasks"), after running a profile (time or event, following tutorial in Chap 8 of the user guide linked above), I only ever see the "System data" tab and the other two don't show up.

Any ideas why this is? I thought it might be a limitation of the Linux version, but the examples shown in the PDF User guide show a system running linux, so I guess that can't be it..

Thanks,

Milos

CodeAnalyst gives "Error starting profile, please try disabling watchdog timer.." (and the latter doesn't work)

milos — 2012-01-01T15:37:41 -05.00

Hi,

I'm having a problem with running an app in CodeAnalyst, on RHEL 5. When I configure a run, and press the "Play" button in CodeAnalyst, a window with the following error pops up:

"Error starting profile (window titlebar): Please try disabling the watchdog timer by running

opcontrol --deinit

echo 0 > /proc/sys/kernel/nmi_watchdog

and try running the profile again. (NOTE: root permission required)"

This is my setup:

1. I am running RHEL 5.7:

[milos@precursor4 ~]$ cat /etc/redhat-release

Red Hat Enterprise Linux Server release 5.7 (Tikanga)

2. I downloaded the RPMs for RHEL5U6 for CodeAnalyst and for the Kernel Modules from the AMD website:

wget http://download2-developer.amd.com/amd/CodeAnalyst/CodeAnalyst-3_1_4_64-RedHatEnterpriseServer5U664bit-Public.bin.rpm

wget http://download2-developer.amd.com/amd/CodeAnalyst/CodeAnalyst-KernelModule-3_1_4_64-RedHatEnterpriseServer5U664bit-Public.bin.rpm

3. I installed both modules as a system user with sudo access using rpm -iv rpmname (first CodeAnalyst, then the Kernel package)

4. I set up the path as instructed, checked that the CodeAnalyst libraries are listed in the ld.so.conf file, and used camanager to add myself as a code analyst user (that seemed to run fine.

5. Then I ran CodeAnalyst from my account without using sudo and it loaded. When I set up a configuration and tried to run it, the error above came up.

6. I tried to do as instructed, and was told I couldn't do this ("permission denied") whether I used sudo or not to try to follow the instructions.

Could anyone shed light on 1) why the error came up, and 2) why I'm not able to follow its instructions? (or even whether I should need to)?

Many thanks for your help in advance.

====

This note added to this post: I just figured out that following the instructions the code gives you above does work (echo 0 > nmi_watchdog), but only if you actually log in as root (doesn't work to run this command using sudo). Furthermore, I have to run this command *each* time I want to run a profile (hit the play button in CA) -- even if I haven't quit and restarted CodeAnalyst in the meantime. Therefore, although I got it to work, it doesn't appear this is the right way to run CodeAnalyst, so any help is still gratefully appreciated.

What is the best strategy to increase multithreading scaling in case of main memory contention?

bhayes2 — 2011-12-15T08:11:11 -05.00

I am trying to increase the scaling of an application on a 4-processor machine (48 cores), currently the max. speed is achieved with around 32-36 active cores. No I/O except for main memory is used and the task is well suited to scaling.

Obviously the only reason for limited scaling can be the accesses to the main memory.

My question now is: How can I best use Codeanalyst to find the critical locations in the application which are responsible for the contention problems?

Session settings : Arguments - I/O redirection

nicholas_yue — 2011-11-06T18:48:05 -05.00

Hi,

I am attempting to profile an application which requires reading it's input from stdin.

When I tried to supply the following argument (without the double quotes) "< datafile.txt", it does not profile or analyse the application (which I have build with full debug on Windows7 64bit using Visual Studio 2010)

Any advice ?

drill down to C functions

offspring — 2011-10-23T18:21:15 -05.00

Hi all,

I am a newbie to CodeAnalyst and I would really like your help.

As we all know, functions offered by C libraries, like malloc, free etc, have their own code. When I want to analyze a C program with CodeAnalyst, I try to drill down to these functions, specifically malloc, and the only thing I see is a weird assembly code which shows that a call is being made to the code of malloc!!!

Is there a way to see the malloc's code (in C preferably)? Should I include more files in the working directory? Which are these files and how can I include them?

Thank you all

Oprofile collected no samples

VincentSC — 2011-10-10T10:16:44 -05.00

The program runs (I selected "show app in terminal" to be sure), but Oprofile collected no samples.

I run Ubuntu 64bit and trying to profile an OpenCL-program. The program was made with:

make -j16 all

g++ -O2 -g -pg -Wall -fmessage-length=0 -c -o main.o main.cpp

g++ -lOpenCL -lrt -o main main.o

I have no clue where to start looking how to solve this problem. I hope somebody on this forum can help me with giving ideas what to try.

CodeAnalyst 3.3 Visual Studio plugin bugs

JamesLTIOptics — 2011-09-07T16:23:38 -05.00

The profile session setting are populated from the "project properties" but is not expanding VS Property Sheet macros. We receive the error message:

"Unable to find the application to launch, '$(TesterExe)' CodeAnalyst profile aborting."

$(TesterExe) is a macro defined in one of our property sheets and is properly resolved by Visual Studios.

Coverage analysis possible?

bruce_np — 2011-09-06T12:24:33 -05.00

Hi there,

I have a question:

Is it possible to get coverage results with Codeanalyst?
I would need the feature to see the coverage of my unit tests.

In my opinion it should be easy as the task seems for me to be a subset of profiling. (check if some code was executed without recording the time)

Am I right?

Best regards

Download/installation Problem with 32-bit Ubuntu CodeAnalyst 3.x DEB

APIC issues

Cromagnus — 2011-07-21T15:42:51 -05.00

I'm running a Xenon X5550. According to my device manager, I do have an APIC enabled. I don't know whether I have Local APIC enabled, and according to the known issues, this is a requirement, but my BIOS has no options for APIC at all.

When I try to run the sample app, the granularity of profiling only goes down to the TID. There is no callstack below that. I've confirmed that I've built the app in debug as required.

Is there a workaround, or some way for me to get this working? Something I've missed? I shut down VS before installing the newest version of CodeAnalyst.

Install problem for version 3.3. on win xp 64 / VS 2008

Hallo,

I tried to install the latest codeanalyst version (3.3.1016.0774) on a win xp 64 system which also has VS2008 installed.

The installation fails when trying to install the x64 redistributable for VS 2010 with a general installation error. Is this due to me not having a copy of VS2010? If so, how can I get around this issue, as I am not able to upgrade my Visual Studio Version currently. I sadly could not find any older versions of codeanalyst for download either.

[Solved] Page fault in AMD SimNow! - possible caching issue?

xenos1984 — 2011-07-08T13:09:30 -05.00

EDIT: I found the reason for the page fault, and it was not a caching problem. It turned out that I tried to use the "global" flag for PD and PDP entries, where it is a reserved field and must be 0.

---

This problem is driving me crazy for a few days already. My 64 bit kernel code runs perfectly fine on Bochs, QEMU and VirtualBox - but it crashes on AMD SimNow!. So here's what I'm doing:

I have set up a PML4T at physical address 0x112000, so I have CR3 = 0x112000. I use a recursive mapping, so the last entry of the PML4T also points to 0x112000. (Actually it contains 0x112063 - present, r/w, dirty and accessed bits are set.) This means that the PML4T is mapped to 0xfffffffffffff000, the last page of virtual memory.

Now I would like to map a page from my kernel to virtual address 0xffff800000000000 - right at the beginning of the upper half of virtual memory. In order to do that, I need to create some lower-level paging structures for that address. So my kernel does the following (you may skip this - it's just to explain how I end up in the situation I'll describe in the next paragraph):

First, it notices that there is no page table for virtual address 0xffff800000000000. So it requests a free page from the page allocator, and gets one. This happens to be 0x0ff0f000 - somewhere close to the top of my 256MB RAM. It tries to map this page to 0xffffffc000000000 - this is where the page table for 0xffff800000000000 should appear by the recursive mapping I use. It finds that there is no page table for that address either, so it requests another free page, gets 0x0ff0e000 from the and tries to map it to 0xffffffffe0000000 - again, this address results from the recursive mapping, and it denotes both the page table for 0xffffffc000000000 and the page directory for 0xffff800000000000. Once again it turns out that there is no page table for 0xffffffffe0000000, so it requests yet another page, gets 0x0ff0d000, and tries to map it to 0xfffffffffff00000. Now finally, this mapping succeeds. The kernel adds an entry to virtual address 0xfffffffffffff800, which is mapped to physical 0x112800 - the middle of the PML4T. So finally all the other mappings should succeed and I end up with the following (this is what SimNow!'s debugger tells me as well):

[code]Virtual Physical Content
0xfffffffffffff000 => 0x00112000: 0x0000000000112063
0xfffffffffffff800 => 0x00112800: 0x000000000ff0d165
0xfffffffffff00000 => 0x0ff0d000: 0x000000000ff0e165
0xffffffffe0000000 => 0x0ff0e000: 0x000000000ff0f105[/code]

So, if you go through the page mappings, you should conclude that virtual 0xffffffc000000000 is mapped to physical 0x0ff0f000, right? And setting the first entry at 0xffffffc000000000 to some address should map this address to 0xffff800000000000? Well, on Bochs, QEMU and VirtualBox this is exactly what happens, and the mappings are exactly the same as here. (Except that the physical addresses are a bit different.) However, on SimNow! I get a page fault as soon as I try to write something to 0xffffffc000000000 - this is also the address I get reported in CR2. If I ask SimNow!'s debugger for a memory dump at virtual 0xffffffc000000000, it tells me that this page is not mapped.

So, if anybody has a clue what's going wrong, please let me know. I thought about a caching / TLB issue, so maybe I'm doing something wrong when it comes to TLB invalidation? However, I don't know how this can happen. I never access 0xffffffc000000000 before, so there should be no TLB entry. And even if there were a TLB entry, it should be cleared, because I do an "invlpg [rdx]" with rdx = 0xffffffc000000000 between the memory writes to 0xffffffffe0000000 and 0xffffffc000000000 - so that should clear the TLB entry for that address, right?

Now I'm really at wit's end. Does anybody have a suggestion what I should check next? Is there a way to dump the cache contents on AMD SimNow!? I searched the web, but I could not find any.

The paging code can be found in [url=http://xenos.svn.sourceforge.net/viewvc/xenos/trunk/kernel/arch/x86/X86Pager.cpp?view=markup]X86Pager.cpp[/url] and [url=http://xenos.svn.sourceforge.net/viewvc/xenos/trunk/kernel/arch/x86/X86Pager.h?view=markup]X86Pager.h[/url].

Problems using CodeAnalyst API on Windows

pbarham — 2011-05-30T21:24:07 -05.00

I'm trying to find the easiest way to record the HyperTransport Bandwidth counters while a multi-threaded process is running on my 48-core Magny-Cours Windows 2K8 server (64-bit). I would like to be able to plot a graph of HT bandwidth on each link while the app is running, with say one data point every second.

I've tried to find a way to do this with CAProfile and the CA Gui .. but it doesn't seem to be possible.

I just came across the CodeAnalyst API which looks promising. It has the notion of 'Counters' which you can manually sample during a profiling run.

The documentation is pretty minimal (i.e. list of parameters), but as far as I can tell I need to call the following functions in this order:

1) fnEnableProfiling()

2) fnMakeProfileEvent(eventid, mask, ... , true, &performanceEvent)

3) fnSetCountingEvent(core, counterid, EventConfiguration)

4) fnStartProfiling(false, NULL, NULL)

5) while (!done) fnGetEventCount(core, counterid, &count);

6) fnStopProfiling()

7) fnReleaseProfiling()

When I do this, all functions return S_OK, until I get to fnGetEventCount which returns error 8000000a, "The profiler was not currently profiling"

If I add a call to fnGetProfilerState after step 4 it tells me the profiler is stopped, even though fnStartProfiling returned S_OK!

I've also tried coding this up using fnSetCountingConfiguration and fnGetAllEventCounts, but I get very similar errors.

Has anybody else managed to get this API to work? Alternatively, could somebody please suggest a way to either debug this API or obtain the same data using the GUI or command line profiler?

Thanks,

Paul.

CA(Windows): Module not found - records wrong folder names in session files

themac — 2011-04-29T02:04:55 -05.00

My Visual Studio project is located on a virtual drive V: created via SUBST. This makes the project portable between computers.

When I profile this project with CA 3.2 (latest build) the folder names for the executable and the DLLs are stored wrong in the session files. The correct files names are

"v:\develop\project\src\app\debug\bla.exe"

CA stores this name as

"\v\develop\project\src\app\debug\bla.exe"

The DLLs of the project are stored in

"v:\develop\project\src\app\dlls"

but CA writes them as

"\v\develop\project\src\app\debug\bla.dll"

in the session.tdb file. The profiling works, but I cannot drill-down into the DLLs because I get the "module not found" error when CA tries to access one of the DLLs in the project.

I could not get it to work with CA 3.2. With CA 2.76 however, I got it to work by manually correcting the folder names in the session.tdp file in Windows Notepad.

After correcting the folder names, CA 2.76 was able to load the DLLs and to drill-down into the source code even.

In the 3.2, correcting the wrong folder names did not change anything.

Let me know if I can provide more info to help you to solve this. I see here on the forum that I'm not the only one with this problem.

Profile Windows drivers

frank777 — 2011-03-22T10:53:10 -05.00

Hello,

I am trying to profile a release version of a Windows driver (.sys). When I use time-based profile I can see my driver but cannot see the functions called. How do I correctly point CodeAnalyst at the release .pdb file OR do I also need to point it at source code?

Thanks.
